Abstract

Postupak i aparatura za suvo mlevenje čvrstih materijala obuhvataju početno grubo mlevenje čvrstih materijala u kontrolisanom vrtlogu fluidiziranog sloja i usmeravanje finih čvrstih čestica uglavnom uzvodno u vrtložnu zonu mlevenja i mlevenje naviše usmerenih čvrstih čestica u vrtložnoj zoni mlevenja pomoću provodjenja dela čestica kroz vrtložnu zonu mlevenja. Vrtložna zona mlevenja obuhvata bar jedan uzastopno vertikalno postavljen stupanj mlevenja koji obuhvata prevodjenje čestica naviše kroz bar jednu horizontalnu vrtložnu zonu anularnog medjuprostora koji je definisan pomoću stacionarne ploče sa kružnim otvorom, zatim čišćenje naviše krećuće smeše proizvoda pomoću eliminisanja grubljih čestica pomoću gravitacionog razdvajanja sa centrifugalnim potiskujućim ventilatorom i podvrgavanje zaostalog dela naviše usmerenih čestica u vertikalni vrtlog rotirajućeg polupropustljivog srtedstva koje je definisano pomoću rotirajućeg sistema koji sadrži sito sa širokim otvorima.The process and apparatus for dry milling of solid materials include initial coarse milling of solid materials in a controlled fluidized bed vortex and directing fine solids mainly upstream to the vortex milling zone and milling upward directed solid particles in the vortex milling zone by conducting particle particles through the vortex zone. The whirling milling zone comprises at least one consecutive vertically arranged milling step comprising conveying the particles upwards through at least one horizontal annular interstitial zone defined by a stationary circular aperture, then cleaning the upward moving product mixture by eliminating coarse particles by gravity separation fan and subjecting the residual portion of upwardly directed particles to a vertical vortex of rotating semi-permeable means defined by a rotating system comprising a wide-aperture sieve.
